All results in table account for missing data using multiple imputation methods.
Follow-up outcomes at 3- and 6-months were analyzed together. Regression models include records for each of the two follow-ups per participant. Models account for clustering of responses within individual and adjust for baseline values of the outcome, race/ethnicity, age, gender, which survey (3-month or 6-month) the response came from, and time elapsed between the end of treatment and the follow-up survey response.
For continuous outcomes, effect size is the coefficient divided by the standard deviation of the outcome for combined follow-up data. For dichotomous outcomes, the effect size is the log of the odds ratio divided by 1.81.
